We covered the ticket FAQ for BlizzCon a few days ago, but there is more news up on Blizzard's official site about the event we all want to attend later this year. They've got an early list of developer panels to browse through, and there are sessions planned, as you'd expect, for Diablo III, Starcraft II, and World of Warcraft (though there aren't any surprises -- if they are going to do a "next expansion" demo panel, obviously we won't know until we look in the programs that weekend). Zarhym has also posted links to the usual contests, tournaments, and information on how to order up the DirecTV coverage.
Unfortunately, it's all pretty rote -- these are basically skeleton pages from what Blizzard did last year, and there's no actual information specific to BlizzCon '09: what the DirecTV purchase might get you, or any new events coming up. But if you haven't been to BlizzCon before, these pages will start giving you some idea of what you'll find there, from the lore and art panels (hint: any panel called "lore" usually has Chris Metzen being extremely entertaining, and any panel with "PvP" in the title will involve people asking question after question to the devs about why one class -- usually Paladins -- is over- or underpowered) to the ongoing competitions you'll see around the event all weekend.
And heck, if you have been to BlizzCon before, maybe these scant notes on what is happening will get you even more excited. Ticket sales begin next weekend -- good luck to everyone trying to buy.
